antto wrote::shock: uhm..
i don't have a "mod" .. i'm just writing code and flashing it onto the x0xb0x CPU via USB
if you don't need the 303 (you gonna throw it away) sure, send it to me ;P~
textile is doing the actual CPU mod, it's a small PCB containing the new (bigger) CPU chip which has to be connected to the x0xb0x (thus the original x0xb0x CPU removed)
as for the firmware.. there are some issues..
TB-303 has 24 buttons, and 2 switches
x0xb0x has 23 buttons, 2 switches and 1 tempo encoder (with a button)
and there is a huge difference in the number of LEDs they have
so the n0nx0x code would have to be modified in order to work on a 303
EDIT: also, n0nx0x can't do some things the same way as on a 303 because of the number of buttons and how they are placed on the panel, so some changes/compromises had to be made

All those are just analog controls independent of the CPU
antto wrote:well i'm trying to mimick the 303 sequencer behaviour in depth as well as add new features or improve some aspects of the old one (there are 16 additional LEDs so why not show the user where in the pattern he is..)
but the difference in the buttons is really nasty:
it's only the section at the right..
x0x needs one more button there, but there isn't such
the compromise was to merge TIME MODE and BACK into the same button
thus.. more compromises must be made in the code
like.. in PitchMode on a 303 you can press BACK and go back 1 step
you can also press TIME MODE and go to TimeMode immediately
in n0nx0x i have to chose either Back or TimeMode (or use a key combination)
that sucks but it's the only way right now..
antto wrote:the x0xb0x adafruit firmware uses MIDI-Out (it sends what it plays as midi notes) (stable)
the SokkOS firmware uses MIDI-Out too (stable)
n0nx0x currently (beta 1.02) does not have MIDI-Out (NOT stable)
so if you planned to use n0nx0x for this.. you'd need to use the CV/Gate (and Accent) outputs from the x0x and have a CV/Gate/Accent INPUTs on your 303 (mod needed)
